摘要： A method of separating oil from a composition containing an oil and water emulsion, by adding a separation additive which is a fatty ester of alkoxylated glycerol, and performing at least one oil separation step. The method is particularly suitable for separating corn oil from stillage produced in a corn ethanol mill.

摘要： A method of inhibiting asphaltene precipitation and/or deposition in a hydrocarbon, preferably crude oil, by adding to the hydrocarbon a polyester asphaltene dispersing agent which is the reaction product of an alk(en)yl substituted succinic anhydride wherein the average number of succinic groups per alk(en)yl group is less than 2.0, and at least one polyol.

摘要： A method of separating oil from a liquid stillage is disclosed. The stillage includes an aqueous phase and an oil phase. The method comprises adding a separation additive to the stillage and performing at least one separation operation on the stillage to separate an amount of the oil phase from the stillage. The separation additive comprises an ester of an alkoxylated non-cyclic polyol and a fatty acid.
